The humanitarian crisis in Niger is worsening in 2018 and a scale-up of humanitarian aid is urgently required, as indicators across multiple sectors are deteriorating. Acute rainfall deficits last season in several regions of the Sahel and armed attacks in border regions with Burkina Faso and Niger have uprooted hundreds of families in recent months, adding to the devastation by the long-running conflict around the Lake Chad Basin. Chronic vulnerabilities related to food insecurity, malnutrition, population displacement, epidemics and floods are being compounded by Boko Haram-related violence in the regions bordering Mali and in the Diffa region in Niger. Overcrowding in camps and displacements sites have worsened the living conditions and exacerbated protection risks faced particularly by children and women. In 2018, an estimated 2.3 million people, including 1.2 million children, will be affected by one or more of the crises impacting Niger. In Diffa, gender-based violence (GBV) has worsened in overpopulated camps. UNFPA is leading GBV sub-cluster and is actively participating in coordination meetings.
